Vedclass · Answer

(C) homologous series is a group of organic compounds having the same functional group and similar chemical properties,where each successive member differs by a $CH_{2}$ unit.For alkanes,the general formula is $C_{n}H_{2n+2}$.$CH_{4}$ $(n=1)$ follows $C_{n}H_{2n+2}$.$C_{2}H_{6}$ $(n=2)$ follows $C_{n}H_{2n+2}$.$C_{3}H_{8}$ $(n=3)$ follows $C_{n}H_{2n+2}$.$C_{4}H_{8}$ follows the general formula $C_{n}H_{2n}$,which represents an alkene.Therefore,$C_{4}H_{8}$ belongs to a different homologous series.

Which of the following does not belong to the same homologous series?
